小数视力≥1.0、对数视力≥5.0 都是正常范围
相当于我们常说的 “1.0 视力”
球镜(S):0.00 表示无近视 / 远视
“-” 是近视“+” 是远视
(比如 - 2.00 就是 200 度)
柱镜(C):0.00 代表无散光
轴位(A):只有散光时才有意义
0-180° 的数字表示散光方向
瞳距(PD):成人一般 55-70mm
配镜时这个数据超重要!
Snellen chart: Decimal ≥1.0 or logarithmic ≥5.0 = normal (\"20/20 vision\").
Sphere (S): 0.00 = no myopia/hyperopia; \"-\" = myopia (e.g., -2.00 = 200°), \"+\" = hyperopia.
Cylinder (C): 0.00 = no astigmatism; numbers = astigmatism present.
Axis (A): 0-180° (only with astigmatism) = direction of astigmatism.
PD: 55-70mm (adults) = key for glasses fitting.
